Sars-Severe Acute Respiratory Syndromes, between
November 2002 and July 2003, an outbreak of SARS in Hong Kong nearly became a
pandemic, with 8,273 cases and 775 deaths worldwide (9.6% fatality) according
to the World Health Organization (WHO). Within weeks, SARS spread from Hong
Kong to infect individuals in 37 countries in early 2003. And is said may still be present in its natural host
reservoirs (animal populations) and may return to the human population.

Research on it has not stopped,including Chinese Medicine.It is said that Chinese herbs can inhibit
the proliferation and strengthen the human immune virus, and so on to play a
very good antiviral activity.

However,a new virus that is potentially more
deadly than Sars emerged,warn scientists after second Briton dies
taking death toll to 11.The following image shows a microscope image of
coronavirus:

The mysterious coronavirus, which has
emerged in the Middle East, attacks the respiratory system and was only
identified six months ago. So far there have been 11 deaths - with the World
Health Organisation this week saying a second British man has died.

Unlike Sars, the new virus affects many
different organs in the body, killing cells extremely quickly. The source of
coronavirus is not known, but experts believe it originated in bats. Animals
which could host the virus include monkeys, pigs and even rabbits .

Shopping online has become very popular for
its convenience , more options and cheaper than local store.But there are
always something that make you uncomfortable. You don't know about the actual
quality of the product is one of the problems.So you choose and choose, end up
with still can't decide whether to buy it or not.You wasted time and do nothing.Here is an article which takes
electronic products as an example, proposing an improvement:

The need for effective and efficient mining
of online reviews cannot be overemphasized. This position is as a result of the
overwhelmingly large number of reviews available online which makes it
cumbersome for customers to read through all of them. Hence, the need for
online web review mining system which will help customers as well as
manufacturers read through a large number of reviews and provide a quick
description and summary of the performance of the product. This will assist the
customer make better and quick decision, and also help manufacturers improve
their products and services. This paper describes a research work that focuses
on mining the opinions expressed on some electronic products, providing ranks
or ratings for the features, with the aim of summarizing them and making
recommendations to potential customers for better online shopping. A technique
is also proposed for scoring segments with infrequent features. The evaluation
results using laptops demonstrate the effectiveness of these techniques.

A Chinese fishmonger was going about his
business when he randomly discovered a bomb... inside the stomach of a squid he
was gutting. Apparently, a three-pound squid had swallowed an eight-inch bomb
on accident. The bomb was live.

Fortunately, the fishmonger managed to
escape unscathed. His knifework discovered the bomb which he speculates got in
the squid's stomach because the squid had mistook it for "small fish and
prawns". The fishmonger hilariously added:

"Perhaps
he thought the bomb was his favourite food and gulped it down. He certainly had
a big belly when he was caught."

What's fascinating is that no one knows
where the eggplant shaped bomb originated from. Local authorities have assumed
that it was an explosive dropped off by fighter jets but the bomb is undated.
Even though its age was unknown and that it didn't look like a "bomb"
(in the sense of what you imagine when you think bomb), it was still active and
could have been detonated.

According to wokv “Thousands of
Jacksonville’s cancer patients may soon get some financial relief for their
treatments.”

It is undoubtedly a good news for Jax
cancer patients.But is the fiscal subsidies the only way to easing the burden
on treating an illness?No , Suman Hazarika( International Hospital, Guwahati,
India) approach the question in the perspective of sociology.

He argues in the paper< Profit fromSickness: The Case of Technology-Driven Healthcare > that remedies to these
crises demand radical a U-turn to the system itself wherein the health care
seekers rather than the health care providers would occupy the center stage.He
thinks in this way,it can reduce the treatment cost largely!

The Out of Africa hypothesis argues that
every living human being is descended from a small group in Africa, who then
dispersed into the wider world displacing earlier forms such as Neanderthal.
The Out-of-Africa theory was bolstered in the early 1990s by research on
mitochondrial DNA studies by Allan Wilson and Rebecca Cann which suggest that
all humans ultimately descended from one female: the Mitochondrial Eve.

In 2007,there is a research claimes that ancient
big drought in Africa supports Out of Africa hypothesis. However,there are more
voice that against the hypothesis.For example，”Out of Africa is a
low-level of pseudoscience”” Out of Africa results from the ignorance”.Why
there are so much disapproval?Maybe the following article can provide clues:

Our consideration of human haplogroups, and
our analysis of the dynamics of the Y-chromosome nucleotide flow from primates
to humans during the evolution of genus Homo has shown that a common ancestor
of the majority of present day human males, both African and non-African, lived
approximately 160,000 years ago. The haplogroup of this common ancestor has
been identified as the α-haplogroup, which is equivalent or close to
haplogroups A1/A1b in the current phylogeny. The archaic lineages (currently
summarily designated A0) descend from an ancestor who lived no later than
180,000 years ago, and probably much earlier. The α-haplogroup and the A0 lineages
have significantly different nucleotide patterns, and they certainly did not
descend one from another. Furthermore, our research points up the areas of
mutations in Y-chromosome in H. sapiens, which allows us to use chimpanzee MSY
(the male-specific region of the Y-chromosome) as a proxy for genus Homo’s
common α-haplogroup ancestor. When we studied slow mutating 16-marker
haplotypes, we discovered that chimpanzees and present day humans had a common
ancestor 5.5 ± 0.9 million years before the present. It is clear that, when
they are compared to loci in other primates, such as gorillas, orangutans, and
macaques, many human Y-chromosome loci have been conserved from our common
ancestor. Results of our analysis of haplotypes, conserved (ancestral) nucleotides,
and SNPs suggest that there is no reason to believe that ancestors of
non-Africans (β-haplogroup, i.e. haplogroup BT and its downstream haplogroups)
descended from haplogroups A0, A1a, or any other African haplogroup. The data
are adequately described by a model which shows that the African lineages and
non-African lineages diverged from the α-haplogroup approximately 160,000 years
before the present and that the Y-chromosomes of the two groups have evolved
independently (in terms of Y-chromosome) since then. We have no indication of
where the common ancestor of the α-haplogroup lived; he could just as easily
have lived in Europe, in Asia, or in the Middle East, as in (less likely)
Africa. We believe that all the presuppositions posited in support of the
Out-of-Africa hypothesis fail to hold up under simple scrutiny. This study
shows that the Out-of-Africa hypothesis has not been adequately substantiated.
The common assertion that “anatomically modern humans came out of Africa some
70,000 years ago” has never been convincingly calculated or determined
otherwise; our research suggests that it is incorrect.

Indian
parliament passes stricter law on sexual violence.In December 2012, India had
occurred fatal gang rape of a young woman on a bus which shocked the world. Later on,more dastardly
gang rape occurs in this country.Even some female tourist in India from other
country also became a victim.Finally,according to The Huffington Post,”
Legislation makes crimes of stalking and sexual harassment and provides for the
death penalty for fatal rape attacks”.

Sexual violence is one of the acts of
violence.We may wonder what caused the violent?Family effects? Personal
character?Or Aggressive Trait Responsible for Violence?Is violent movies a murderer?
The last two factor,there is a controversy:

A research from SCIRP puts forward that “violent
movie could effectively elicit implicit aggression for adolescents who were
highly aggressive, but not for nonaggressive adolescents.”

Alcohol is bad for our health, this is an
old ,old topic.But few people know how does it do harm to our health.

Its effects can be divided into acute and
chronic. Acute poisoning often happens in the oral.There are 4 stages: excited,
hypnosis, anesthesia, choking.When in the third and forth stage, sufferers may
experience loss of consciousness, pupil dilation, irregular breathing, shock,
heart failure and stop breathing cycles. Chronic effects often happens when one
exposure to high concentrations of this product for a long time.It often causes
membrane irritation of nose, eyes, mucous,even headache, dizziness, fatigue,
eas ily excited, tremor, nausea, etc. Long-term alcohol abuse can cause
multiple neuropathy, chronic gastritis, fatty liver, cirrhosis of the liver,
myocardium damage and organic psychosis and so on.

Besides the above effects, a research from Scientific
Research Publishing found some other new effects of acute and chronic ethanol(the
experiment is based on Hippocampus).The following is the general:

In the present study, we concentrate on the
chronic effects of ethanol on the hippocampus. We demonstrate how the neuronal
activity underlying food-acquisition behavior is modified after chronic ethanol
treatment, and how the hippocampus subserves formation of newly-formed
alcohol-acquisition behavior. Neuronal activity in CA1 was more sensitive to
chronic ethanol than the Dg area. Acute administration of ethanol had a
normalizing effect on the chronically-treated animals: their performance and
the hippocampal neural activity approached a normal range. The sets of neurons
involved in food-acquisition behavior formed before chronic ethanol treatment,
and those involved in alcohol-acquisition behavior formed after treatment
significantly overlapped supporting the view that the neuronal mechanisms of
pre-existing behavior provide the basis for the formation of new behavior.
Additionally, we also discovered alcohol-acquisition selective neurons.
Assuming that the formation of new neuronal specializations underlies learning,
we believe that alcohol-selective neurons are specialized during the formation
of alcohol-acquisition behavior. Our data demonstrate several new findings on
the effect of acute and chronic ethanol on hippocampus activity, and how the
neuronal activity relates to behavior before and after ethanol treatment.

What is a healthy diet? This is a matter of
concern to everyone.So we often read some health book.But a research from SCIRP
raises doubt: Have we been giving the wrong dietary advice?The following is the
background, methods, findings ,interpretation of the research:

Background: Since 1984 UK citizens have been advised to reduce total dietary
fat intake to 30% of total energy and saturated fat intake to 10%. The National
Institute of Clinical Excellence [NICE] suggests a further benefit for Coronary
Heart Disease [CHD] prevention by reducing saturated fat [SFA] intake to 6% -
7% of total energy and that 30,000 lives could be saved by replacing SFAs with
Polyunsaturated fats [PUFAs]. Methods:
20 volumes of the Seven Countries Study, the seminal work behind the 1984
nutritional guidelines, were assessed. The evidence upon which the NICE
guidance was based was reviewed. Nutritional facts about fat and the UK intake
of fat are presented and the impact of macronutrient confusion on public health
dietary advice is discussed. Findings:
The Seven Countries study classified processed foods, primarily carbohydrates,
as saturated fats. The UK government and NICE do the same, listing biscuits,
cakes, pastries and savoury snacks as saturated fats. Processed foods should be
the target of public health advice but not natural fats, in which the UK diet
is deficient. With reference to the macro and micro nutrient composition of
meat, fish, eggs, and dairy foods the article demonstrates that dietary trials
cannot change one type of fat for another in a controlled study. Interpretation: The evidence suggests
that processed food is strongly associated with the increase in obesity,
diabetes, CHD, and other modern illness in our society. The macro and micro
nutrients found in meat, fish, eggs and dairy products, are vital for human
health and consumption of these nutritious foods should be encouraged.

Palaeopathology research is of great
difficulty for 2 reasons:1) Most of the ancient biological remains retaines
only a skeleton part(Including the fossil),with only a small amount of the soft
tissue left(such as ancient human mummies, frozen corpse, wet wax and peat
tanning corpse,ect);2) Some pathological information can not be extracted for the
preservation of the human skeleton various with different regions.Although with
so many problems that hard to solve,scientists still devote themselves to the
study.Because the study of the history of a disease, will contribute to the
modern human for the prevention and treatment of the disease.A research from SCIRP presents
a case study of differential diagnosis of pathological conditions which have
been observed on the bones of the skeleton of a 30 - 34 years old female from
Tell Masaikh (Syria).And use morphological, histological, radiological and
molecular methods to assess the pathological lesions.In the end,the research illustrates
the complications associated with differential diagnosis of pathological
conditions from ancient bones.

How to lose weight is always a hot topic!There
are all kinds of ways ,and medince of losing weight. Even a fantastic study
states: clicking mouse can be helpful to weight lose,however overruled.The
study on weight lose are in an endless stream.Because,not only femal need to
lose weight,male also need nowadays.

A
research from SCIRP state that the attitudes towards losing weight make a
difference:

To investigate motivators and strategies of
adult weight loss or management, 1805 adults aged 18 - 65 were asked by
computer assisted telephone interviews about their weight management behavior
during the previous four weeks. High levels of importance to reduce risks
associated with chronic diseases such as cancer, heart disease and diabetes
were observed, although were indistinguishable between people attempting or not
attempting to lose or maintain weight. Results showed that BMI was the
strongest predictor of attempting to manage weight irrespective of age and,
compared with males, females were more likely to attempt weight management at a
lower BMI. Among the weight management group, the most popular weight
management strategy was to choose healthier food options (77% and 70% for
females and males respectively). With the weight management group also more
likely to be monitoring the amount of food they consume, limiting portions
sizes and tracking their physical activity participation compared with people
not managing their weight. The current study showed that the likelihood of
weight management within four weeks prior to the survey peaked for both sexes
when BMI reached obese levels, (BMI = 30 - 39.9), suggesting that among people
categorised as obese most were attempting to manage their weight. The results
also suggest that at least some adults were not attempting to maintain their
weight in the four weeks prior to the survey, irrespective of their BMI status.
The implications of these findings suggest more effective approaches to weight
loss and maintenance could focus on strategies that directly address the
benefits and motivations of weight loss and weight maintenance, rather than
focusing on conveying the risks of being overweight and the importance of
avoiding chronic disease.

Are you ever curious about "Will brain
transplants ever be possible? And, after the transplant, who would the person
be – would they be the person whose brain was transplanted or the person whose
body got the new brain?" On top of that, would continuous brain
transplants be a good way to keep a mind alive forever? To the scientists.

Angelique
Bordey, PhD, Professor of Neuroscience, Yale
University School of Medicine:

1. [Will there ever be brain transplants?]
Not sure. Why not. Spooky though. You have to change not just the brain but
also the spinal cord otherwise forget walking.

2. [Would the person's identity be
maintained?] Psychological horrible as we grow our brain/mind to our body. So
personality could change just due to the psychological shock.

3. [Could we stay alive forever this way?]
No. our brain is aging as fast as the rest of our body. We will be able to
replace organs heart lungs kidney…..with artificial ones but not the brain. We
will all end up with cancer or Alzheimer or another neurodegeneration. Back to
baby stage.

The bigger question: do we want to live
forever? Why would we. Dying gives us a reason to live.

Khalid
M. Abbed MD, Professor of Neurosurgery, Yale:

Human brain transplants are very far away
but may someday be possible. A key step in making brain transplants possible is
the ability to connect nerve fibers from the transplanted brain to the native
spinal cord. This is very difficult and is one of the main reasons why severe
spinal cord injuries are so devastating and usually permanent.

If brain transplants were possible, the
identity of the person would undoubtedly change and be more like the identity
of the donor of the transplanted brain. This is because, unlike a transplanted
heart, the brain is where identity and personality are stored.

Konstantin
Slavin MD, Professor of Neurosurgery, University of
Illinois at Chicago:

Yes, I do believe the day will come when
there will be a "whole body transplant" – so the brain of a person
will be given a new body (and not the other way around). If this happens, the
identity and personality of the original brain owner will be allowed to continue
within new physical body, natural or artificial. This will not keep the person
alive indefinitely as the brains age and degenerate over time – and I would not
be very optimistic about our ability to stop aging completely.

[Dr. Slavin also referred us to the science
fiction novel "Professor Dowell's Head," by Russian science fiction
writer Alexander Belyaev. Someone please leave a book report in the discussion
section.]

THE VERDICT: Yes! Neurosurgeons are
optimistic about the theoretical possibility of a human brain transplant,
although it does not seem to be coming in the near term. If you had your brain
transplanted into another person's body, you would maintain your own identity,
although you might be somewhat traumatized and fucked up by the experience. And
no, transplants will not allow you to live forever—and really, would you want
to?? (A: No, only until they invent robot sex.)

According to mailonline, disrupted sleep
can be an earlier sign of Alzheimer’s
disease than memory loss. Disrupted sleep may be less sleep, but napped more
often.Moreover,this disease has been younger tendency.Except disrupted sleep
and memory loss,does this disease has any other prognostic? How to detect it
and and prevent as soon as possible? A research focuses on the possibility of early detection of AD-specific vascular and
atrophic brain changes in families which have a tendency to inherit the
disease.The following is the general content:

The research included three families with
AD inheritance. All patients underwent: cognitive function assessment (MMSE),
determination of dementia severity (CDR) and AD stages (TDR), computed tomography
(CT), magnetic resonance imaging (MRI), scintigraphy of the brain (SG),
rheoencephalography (REG), and cerebral multigated angiography (MUGA). All
patients with different AD stages, as well as their descendants, have specific
atrophic changes in the temporal lobes of the brain. The degree of these
changes increases as AD becomes more severe and ranges from 4% - 8% (TDR-0) to
33% - 62% (TDR-3) of the total mass of a healthy person’s temporal lobes.
Simultaneously, the patients examined have changes of microcirculation
manifested by reduction of the capillary bed in the temporal and
frontalparietal regions, the development of multiple arteriovenous shunts in
the same areas, early venous dumping, anomalous expansion of venous trunks that
receive blood from the arterialvenous shunts, venous stasis on the
frontoparietal boundary. Similar changes are found among AD patients’
descendants aged 8 - 11, the only difference being in the degree of temporal
lobes atrophy which is 4.7%. This proves that microcirculatory disorders are
primary and atrophic changes of the temporal lobes are secondary in AD
development. The data obtained indicate that the examination of AD patients’
relatives should begin well before the possible manifestations of the disease,
even in childhood. It will allow to reveal the possibility of inheritance and
the signs of the disease at the earliest possible stage and to begin its
treatment in time.

I hope this research can be helpful to the prevention and treatment of Alzheimer’s
disease.

A new research reveal that : human sperm
are generally at their healthiest in winter and early spring.

Based on samples from more than 6,000 men
treated for infertility, researchers writing in American Journal of Obstetrics
& Gynecology found sperm in greater numbers, with faster swimming speeds
and fewer abnormalities in semen made during the winter, with a steady decline
in quality from spring onward.

The scientists said :” If there is a
seasonal pattern, that knowledge may ‘be of paramount importance, especially in
couples with male-related infertility struggling with unsuccessful and
prolonged fertility treatments’””.

The World Health Organization defines anything
over 16 million sperm per milliliter of semen as a normal sperm count.According
to this criterion, Eliahu Levitas found that men produced about 70 million
sperm per milliliter of semen during the winter. About 5 percent of those sperm
had "fast" motility, or swimming speed, which improves a couple's
chance of getting pregnant. That compared to the approximately 68 million sperm
per milliliter the men produced in the spring, of which only about 3 percent
were "fast."

In animal studies, seasonal changes in
sperm production and fertility have been demonstrated,it is rare to link to human.

A report from gizmag RESEARCH WATCH states
that we can make old brains young again with the help of switch molecular.

It’s no secret that juvenile brains are
more malleable and able to learn new things faster than adult ones – just ask
any adult who has tried to learn a new language. That malleability also enables
younger brains to recover more quickly from trauma. Researchers at Yale University
have now found a way to effectively turn back the clock and make an old brain
young again.

As we enter adulthood, our brains become
more stable and rigid when compared to that of an adolescent. This is partially
due to the triggering of a single gene that slows the rapid change in synaptic
connections between neurons, thereby suppressing the high levels of plasticity
of an adolescent brain. By monitoring the synapses of living mice for a period
of months, the Yale researchers were able to identify the Nogo Receptor 1 gene
as the key genetic switch responsible for brain maturation.

They found that mice without this gene
retained juvenile levels of brain plasticity throughout adulthood and by
blocking the function of this gene in old mice, the researchers were able to
reset the old brain to adolescent levels of plasticity. This allowed adult mice
lacking the Nogo Receptor to recover from brain injury as quickly as adolescent
mice, and also saw them master new, complex motor tasks faster than adult mice
with the receptor.

The researchers also showed that the Nogo
Receptor slows the loss of memory, so that mice without the Nogo Receptor lost
stressful memories more quickly than those with the receptor. The researchers
say this suggests that manipulating the receptor could help treat those
suffering post-traumatic stress disorder.

“We know a lot about the early development of the brain. But we know
amazingly little about what happens in the brain during late adolescence, said
Dr. Stephen Strittmatter, Vincent Coates Professor of Neurology, Professor of
Neurobiology and senior author of the paper which appears in the journal
Neuron.

At an event this morning, Facebook took the
wraps off the service's latest design. The idea is, as Facebook says, to
"pull back the chrome," simplifying the way the site works and looks.
That means cutting down on all the boxes and lines and shading and sidebars and
lord knows what else litters your homescreen right now. It's more like a mobile
app than ever before; just the stream of news.

And it actually is similar to a news site
in a few ways; it now has different sections, so you can check out what your
friends have been doing in specific categories like music, photos, and games.
They're all kind of individual feeds, which is clever; services like Instagram
(which Facebook owns), plus Vine and Twitter, are much more concise, and this
is a way for Facebook to not be quite so bulky.

And
it looks great! Facebook has not always been the nicest-looking service, but
the cleaner design, paired with larger images and videos, make it perhaps the
most aesthetically appealing version of Facebook yet. Of course, big photos
also mean big ads, which could be irritating.

Facebook's new design will begin rolling
out today, though not all at once.

That is a report from popsci.To facebook there is an another interesting research from SCIRP about Privacy Settings.The following
is the general:

The present study examined disclosure and
use of privacy settings in online social networking profiles as a function of
the media context (i.e., online versus hard copy (paper and pencil) FacebookTM
profiles). Gender was also examined. Overall, participants disclosed more
information when constructing a profile for another person when using a hard
copy paper and pencil format than an online context. Gender differences were
not uniform across media contexts, however, in contrast to traditional
disclosure theory, females censored their disclosures more so than males but
only for some topics. Only 20% of the sample increased their use of privacy
settings. Consistent with patterns of disclosure, descriptive comparison
suggests that more settings were employed in the paper and pencil than online
context and more privacy settings were employed by females.

Calcium and other vitamins and minerals in
milk make it an important part of a healthful diet for people of all ages. The
benefits of drinking milk include strengthening bones, improved cardiovascular
and oral healthand even relief from PMS.But with the appearance of adulterated
milk, it become a threat of our health,especially for infants. How to Identify adulterated milk is a topic many
people are deeply concerned with.The following is a research from scientificresearch publishing about the identification of Calcium and Sodium Behavior to
Identify Milk Adulteration:

A fast and direct method for determination
of milk adulteration by monitoring of calcium and sodium concentrations
variations was described. Milk samples were furnished by a dairy company
located at São Carlos (São Paulo State, Brazil) and and spiked with tap-water,
whey, hydrogen peroxide, synthetic urine, urea and synthetic milk in the ranged
from 5% to 50% (v/v), expect for caustic soda. Caustic soda was added in the
milk until establish the original pH. The milk samples were analyzed by using
flame atomic absorption spectrometry (FAAS) and no acid digestion process was
required. Results showed a significant decrease in the Na and Ca concentrations
with addition of synthetic milk and tap-water, a nonlinear variation with
addition of synthetic urine, whey and hydrogen peroxide and a largest increase
in the Na concentration with addition of NaOH. Correlation between Na and Ca
concentrations in pure and adulterated milk were evaluated by paired t-test at
a 95% confidence level. Results showed that the method proposed is efficient to
identify samples adulterated with tap-water, caustic soda, synthetics milk and
urine.

This research applies Flame Atomic
Absorption Spectrometry,maybe it is more useful for research worker.

Servant leadership is a leadership
philosophy and also a set of leadership practices. These leaders sets themselves
up as an example, lead by serve; The result is also in order to extend its
service function. Servant leadership Emphasizes service first.

There is a growing concern about the
relationship of servant leadership and employee loyalty recent years, but few
are focusing on the intervening mechanisms between them. Especially in China,
research on such mediating variables is nearly blank. A research from scientific
research publishing , discusses this problem.The following is the part:

We
make our attempt on detecting the role in such relationship by empirical
studies through 186 samples using the structural equation model (SEM) method,
and reach two conclusions: servant leadership is significantly positive
correlated with employee loyalty; employee satisfaction is found to play
mediating role which occupies 77% of the total effect between servant
leadership and employee loyalty. Our result shows that, to improve employee
loyalty, the managers should not only develop their servant leadership style,
but also take into consideration the individual needs to improve psychological
satisfaction.

Connecting bacterial with businesses is a
new idea.Ichiro Matsumura ，Emory University ，proposes businesses research and biological systems research may learn
from each other.The following is the abstract of his research:

Bacteria, like industrial engineers, must
manage processes that convert low value inputs into high value outputs.
Bacteria are not intelligent, so they utilize self-organizing production
systems to accelerate life-sustaining chemical processes. Here I explore two
questions. First, can businesses apply the principles of self-organization?
Second, can operations researchers contribute to our understanding of
biological systems? I explain biochemical concepts in plain terms, illustrated
with a few informative laboratory evolution experiments, and describe the
organizing principles that underlie complex biological systems. I describe the
new disciplines of synthetic biology and metabolic engineering, which offer
opportunities for interdisciplinary collaboration between life scientists and
operations researchers.
